I'm not sure why the error is "No such file or directory" ... colord.service clearly exists. According to Bug 92165 - colord-session: Add a systemd user service corresponding to the D-Bus session service <a href="https://bugs.freedesktop.org/show_bug.cgi?id=92165">https://bugs.freedesktop.org/show_bug.cgi?id=92165</a> "This deliberately does not configure the systemd unit to be started on login: it is still only launched on-demand via D-Bus activation, just like it always was." iiuc, on use of any colord tool, e.g. 'colormgr', the /usr/local/share/dbus-1/system-services/org.freedesktop.ColorManager.service service should be triggered, and then should invoke/start /usr/lib/systemd/system/colord.service What am I missing here? </div>
